Calmare's device is fantastic. True, not everyone responds, but many do.

My wife has intractable coccyx/perineal pain associated with pudendal/sciatic neuropathy and CRPS. We went to St. George for treatment by Dr. Chalmer's staff. The treatments were $150 each, and ideally one undergoes 10 treatments. She did not respond, unfortunately, but we met other patients who do, including a lady from San Diego who suffers from severe CRPS, including a clenched fist. She goes up every month or two for a round of treatments, and returns home pain free (yes, ZERO pain), which lasts up to several weeks and then gradually returns. What she needs (what we all need) is a clinic providing the treatment in her own home town. In time, this will likely happen.

This treatment is definitely worth an inquiry.
